VENTILATING DEVICE.

To at! tel/,om it lmay concern.'

Re it known that I, 'LENA .f\. linoirr, a Citizen ot the United States ot ..'\meriea, and a resident ot Buchanan county, iowa, have invented Certain new and uset'ul linprovements in Ventilating Deviees7 ot which the following a specification.

My invention relates to improvementsl in Ventilating devices, and the objet-t ot' my in'iprtwements is to i'novide a suitable deviee tor application to an opened window, wherel j an entering dra'lt ot air may be de tleeted upwardly, tor more equable distribution throughout a room. and direct dratts npon the inmates avoided. This object l have accomplished by the means whirh are hereinafter described and claimed. and whieh are illustrated in the accompanying drawings, in whieh:

Figure l is a (liagrammatie view ot a portion ot a room provided with an opened window, with my improved detleeting device mounted in said window-easing. vpartly in section. and in use 'tor ehanging the direction ot an entering current" ot" air. Fig. 2 is an enlarged perspective view ot my said detleeting-deviee. showing it' spread open vto its operative position.

My drarli't delleeting-deviee is termed ot two square 'trames7 one being open and oonstrueted ot the pieees (l. fm, e and o. white the other is elosed by a eovering ot' eloth s or other inaterial oft' a suitable nature, and made ot the three pieces e, t) and fie, the lower ends ot the sidepieees /1 and fm being eonneeted to the broad lower pieee o ot' the first-mentioned 'trame by means of hinges a and The openings between the said frames at the sides are closed by means ot cloth coverings a and i'. A staple z' on the bar (Z oit the open it'raine is adapted to reoeive the hook '/1. on the top bar c ot the closed trame. when said trames are closed together. lVhen the trames are separated and spread apart vt'or use, they are held in this position by hooks 7.: hung on eyelets on the inside 'taees ot the side bars of the closed trarne, said hooks engaging det'aehably the eyelets l on the inside `t'aees ot the side bars oft the said open trame. The open box thus 't'orlned is made ot a. proper size to Fit. snugly within the lower part ot a window-easing covering at least the major por- Speeication of Letters Patent.

l tion ol the lower sash, with the open top between the top bars e and projecting into the room.

ln order to insure a elose tit between the bottom and side pieces ot the device with the window sill and easing. l place a strip ot telt or other suitable material (j along the under side o't" the lower bar o, and similar pieees y) and along the bars ma and e where they will eontaet with the easing-strips. t 'lhese strips prevent leakage o'tz air between said bars and the easing` the whole d-ralt passing through the opening ol the said open trame into the deviee. where it is deleeted upwardly by the covering s.

To lseeure the deviee to the easing, small eyelets w are inserted in the window traming` and are detaehably engaged by thehooks 1/ on the tension-springs e, whose other ends are lseeured to the side bars ot the said elosed trame. lt. is obvious, however. that other faslening-means 'tor the parts otthe deviee than those specifically deseribed may be adopted without departing trom the prineiples ot my invention.

.\s shown in the diagrammatic view, a` drat't ol air passing under a raised lower sash yl/ enters the defleeting-device whieh is mounted in the opening between the sill g and easings f, and is deflected upwardly in a direction indicated by the arrows. The air-('-urrent moves toward the Ceiling, where it is again deflected and mingles gradually and evenly with the air ot the room, no part o't the drat't being permitted to impinge upon an oeeupant ot the room. n this way a room is successfully ventilated7 without danger to the oeonpants. dien not in use the deviee may be easily detached from the easing, 'folded7 and laid away, being light and not bulky.

llaving described my invention, what I elaim as new. and desire to secure by Letters Patent, is:

A Ventilating device. comprising av basepieee titted to the lower sill of a windoweasing detaehably, an open rectangular trame supported on said base-piece within said easing and adapted to overlie an opening between said sill and the window in said easing. another reetangular trame hinged to t said base-piece and extending into the room.

collapsible coverings uniting the side uprights of both said frames, a covering for and casing sides to seal the nlerstices belo the seccnd-inentoned rectangular frame, detween the saine and said device.

tuchable .ineens for holding said frames Signed at Independence, lewe., this 17th apart, tensonul connect-ions secured detuchday of March, 1910.

ably between saidA devlce and sind casing, LENA A. BRIGHT. pads mounted 0n the lower Surface of said base-piece and on the outer sides 0f the uprights of the first-mentioned rectangular frame und adapted to Contact With said Sill Titnesses OTTO FENNER, H. M. BRIGHT.
